Specilication describing a new and useful Improvement in Shovel-Flows,invented by GEORGE HOPKINS SMITH, of DesnMoineS, in the county of Polkand State ot' Iowa.

Bly invention has for its object to furnish an improved cast shovel-plowfor cultivators, which shall be so' made as to possess the requisitestrength While leaving its forwardside or.

the plow-seat, by which the plow is secured to the plow-standard. Uponthe rear sides of the side edges are formed short projections, ribs, orthickenin gs, C, extendingfor such a. distance as may be necessary forthrowing out a full corner and giving the requisite strength to theshovel, the. upper parts ofthe side edges., where so much strength isnot required, being made lighter.

The Shovels may be cast of any metal that will give a good toughcutting-edge and a strong back, and will take the highest possibletemper upon the front. Cast-,steel fronts east upon Bessemer-steelbacks, in cast-iron molds, will make the best shovels.

Having thus described my invention, I claim as new 4and. desire tosecure by Letters Patent The shovelplowshare A, having cent-ral rib Band side ribs O C arranged thereon, as and for the purpose described.
